Ping-Pong virus

The Ping-Pong virus (also called Boot, Bouncing Ball, Bouncing Dot, Italian, Italian-A or VeraCruz) is a boot sector virus discovered on March 1, 1988 at the University of Turin in Italy. It was likely the most common and best known boot sector virus until outnumbered by the Stoned virus.

Replication method

Computers could be contaminated by an infected diskette, showing up as a 1 KBbad cluster (the last one on the disk, used by the virus to store the original boot sector) to most disk checking programs. Due to being labelled as bad cluster, MS-DOS will avoid overwriting it. It infects disks on every active drive and will even infect non-bootable partitions on the hard disk. Upon infection, the virus becomes memory resident.

Effect

The virus would become active if a disk access is made exactly on the half hour and start to show a small "ball" bouncing around the screen in both text mode (the ASCIIbullet character "•") and graphical mode. No serious damage is incurred by the virus except on '286 machines (and also V20, '386 and '486), which would sometimes crash during the ball's appearance on the screen. The cause of this crash is the "MOV CS,AX" instruction, which only exists on '88 and '86 processors. For this reason, users of machines at risk were advised to save their work and reboot, since this is the only way to temporarily get rid of the virus.

Italian wine

Italy is home to some of the oldest wine-producing regions in the world, and Italian wines are known worldwide for their broad variety. Italy, closely followed by France, is the world’s largest wine producer by volume. Its contribution is about 45–50 million hl per year, and represents about ⅓ of global production.Italian wine is exported around the world and is also extremely popular in Italy: Italians rank fifth on the world wine consumption list by volume with 42 litres per capita consumption. Grapes are grown in almost every region of the country and there are more than one million vineyards under cultivation.

History

Although vines had been cultivated from the wild Vitis vinifera grape for millennia, it wasn't until the Greek colonization that wine-making flourished. Viticulture was introduced into Sicily and southern Italy by the MycenaeanGreeks, and was well established when the extensive Greek colonization transpired around 800 BC. It was during the Roman defeat of the Carthaginians (acknowledged masters of wine-making) in the 2nd century BC that Italian wine production began to further flourish. Large-scale, slave-run plantations sprang up in many coastal areas and spread to such an extent that, in AD 92, emperorDomitian was forced to destroy a great number of vineyards in order to free up fertile land for food production.
